Unable to make this work in a worker thread

[grrrwaaa]

I have a basic test of the library working, it's great.

I wanted to move the receiver to a worker thread to free up resources on the main thread, but when I do I either get "No data received" timeouts on the receiver.video() call. The exact same code works fine and I receive streams when in the main thread.

Here's the code for "ndi_worker.js"

const { workerData, parentPort } = require('worker_threads')

const grandiose = require('grandiose');
console.log(grandiose.version(), grandiose.isSupportedCPU())

async function run() {
    let sources = await grandiose.find()
    console.log(sources);
    if (!sources.length) return

    let receiver = await grandiose.receive({ source: sources[0], });
    console.log(receiver)

    let timeout = 1000; // Optional timeout, default is 10000ms
    while (true) {
        try {
            let videoFrame = await receiver.video(timeout);
            //console.log(videoFrame);
        } catch (e) { console.error(e); }
    }
}

run()

And to launch it:

const { Worker } = require('worker_threads')
let ndi_worker = new Worker("./ndi_worker.js")

Output:

It's baffling why it would work on the main thread but not on a worker thread. Could there be something in the implementation that assumes main thread somehow?

Are you tried to use data() instead of video() or audio() ?

[grrrwaaa]

Yes, strangely using .data() does work, but .video() does not.
